Description
Drop a Tikka T3 short action into the MDT XRS and you get the best of two worlds. It keeps the familiar silhouette and natural feel of a classic rifle stock, but underneath that textured polymer skin sits a full-length CNC machined 6061 aircraft grade aluminum core. That rigid backbone is paired with a precision V-block bedding system that seats your action the same way every single time, which is where real accuracy gains come from. Installation is about as simple as it gets, with two action screws and no bedding compound to fuss with.
Dialing In the XRS to Fit You
Fit is where this chassis earns its keep. The length of pull adjusts from 13.25 inches out past 15 inches using the included spacers, and the quick-adjust cheek piece lets you set scope height over bore without reaching for tools. Those two adjustments make a big difference whether you are settling in for a long range session or getting a clean cheek weld in a hunting setup. The XRS also ships with both a vertical and an angled grip, so you can swap between them with a few external screws and run whichever feels right in your hands.
Feeding and Mounting on the Tikka XRS Chassis
The XRS runs standard AICS pattern magazines through an easy-to-work ambidextrous latch, so you are not locked into anything proprietary and mags are easy to find. Up front, the roughly 12 inch forend is loaded with M-LOK slots for bipods, ARCA rails, Picatinny sections, or whatever accessories your build calls for. The barrel channel is free floating and will clear contours up to 1.25 inches in diameter, giving you room for a heavier tube if you want one.
At around 3.9 pounds depending on the inlet, the XRS strikes a nice middle ground. It is light enough to carry into the backcountry but stable and solid enough to shoot well off a bag or bipod at distance. For a Tikka owner who wants one setup that does double duty between the field and the range, this is a tough combination to beat.

Frequently Asked Questions
Will the MDT XRS Chassis fit my Tikka T3 without modifications?
Yes, this model is inletted specifically for the Tikka T3 and T3x short action, so it is a direct fit for those actions. Installation uses two action screws and does not require any bedding compound. Just make sure you have the short action version, as this chassis is cut for the short action footprint only.
What magazines does the XRS Chassis use?
The XRS feeds from standard AICS pattern magazines through an ambidextrous latch. These are widely available and affordable, so you are not stuck with proprietary mags. This also lets you run short action calibers like .223 or .308 family rounds depending on the magazine you choose.
Is the MDT XRS light enough for hunting?
At roughly 3.9 pounds depending on the inlet, the XRS lands in a nice middle ground between a lightweight hunting stock and a heavier competition chassis. It is manageable to carry in the field while still giving you a stable, rigid platform for shots at distance. That versatility is a big part of why people pick it for a crossover rifle.
Can I mount a bipod and other accessories on the forend?
Absolutely. The roughly 12 inch forend comes with M-LOK slots built in, so you can attach a bipod, ARCA rail, or Picatinny section for your gear. The barrel channel is free floating and clears contours up to 1.25 inches, giving you room for heavier barrel profiles.
